Final answer:
A type rating is necessary for any large aircraft over 12,500 pounds, turbojet-powered airplanes regardless of weight, and any aircraft mandated by the FAA through aircraft type certificate procedures. Lighter-than-air aircraft and large aircraft under 12,500 pounds do not require a type rating unless other criteria are met.
Step-by-step explanation:
The question focuses on understanding which types of aircraft require a pilot to hold a specific type rating for operation. According to Federal Aviation Administration (FAA) regulations, a type rating is required for the following kinds of aircraft:
- A large aircraft with a gross weight of over 12,500 pounds, except lighter-than-air.
- Any turbojet-powered airplane, regardless of weight.
- An aircraft specified by the FAA through aircraft type certificate procedures.
Based on these criteria:
- A large aircraft with a gross weight of less than 12,500 pounds does not require a type rating unless it is turbojet-powered or specifically mandated by the FAA.
- A turbojet-powered airplane requires a type rating.
- A lighter-than-air aircraft does not require a type rating based solely on its weight.
- Any aircraft that the FAA specifically lists through aircraft type certificate procedures require a type rating.
